Connector housing with short-circuit bridge

Abstract

A connector housing has a longitudinal axis and includes a first housing portion, having a front end face and a rear end, and at least two accommodation chambers extending parallel to the longitudinal axis, and receiving respectively an electrical contact element, and having a connector tab. The accommodation chambers have, respectively, an insertion opening for a mating contact element and an exiting opening for the connector tab, open to the front end face. An elastic locking arm is provided for each accommodation chamber for retaining the contact element in the accommodation chamber. A second housing portion is formed integrally with the first housing portion and forms an accommodation chamber, into which a portion of a housing of a mating connector can be inserted. The second housing portion has contact elements having female contact terminals, which can be electrically connected to the contact elements. A short-circuit bridge, made from an electrically conductive material, is retained in the first housing portion and includes for each contact element an elastic contact arm. The contact arms are connected to each other and serve to contact the connector tabs. In an initial position, a front holder supports the contact arms in the lifted position and in the final position leaves these unloaded, so that these can contact the connector tabs.

1. A connector housing having a longitudinal axis, comprising:
 a first housing portion, having a front end face and a rear end; 
 at least two accommodation chambers, extending parallel to the longitudinal axis and receiving respectively an electrical contact element, and having a connector tab, wherein the accommodation chambers have, respectively, an insertion opening for a mating contact element and an exiting opening for the connector tab, opening to the front end face; 
 an elastic locking arm for each accommodation chamber for retaining the contact element in the accommodation chamber; 
 
     a second housing portion, which is formed integrally with the first housing portion, and forms an accommodation chamber, into which a portion of a housing of a mating connector can be inserted, having mating contact elements, comprising female contact terminals, which, respectively, can be electrically connected to the contact elements;
 a short-circuit bridge, which is made from an electrically conductive material, retained in the first housing portion, comprises for each contact element an elastic contact arm, wherein the contact arms are connected to each other and serve to contact the connector tabs; and 
 a front holder, which can be displaced between an initial position and a final position along the longitudinal axis, which holds in the initial position the contact arms in a lifted position and leaves the same in the final position unloaded, so that these can contact the connector tabs. 
 
   
   
     2. The connector housing according to  claim 1 , wherein the front holder is formed frame-like and is taken-up in the final position at least partially in a countersunk manner in the front end face. 
   
   
     3. A connection comprising:
 a connector housing according to  claim 1  and a mating connector, to which at least one second separation element is arranged, which separates the contact of the contact arms to the connector tabs while connecting to the connector housing. 
 
   
   
     4. The connector housing according to  claim 1 , wherein the front holder has at least one first separation element, which holds in the initial position the contact arms of the short-circuit bridge in the lifted position and releases the same in the final position. 
   
   
     5. The connector housing according to  claim 4 , wherein for each contact arm a first separation element is provided. 
   
   
     6. The connector housing according to  claim 1 , wherein the front holder has struts extending parallel to the longitudinal axis and supporting a crossbar. 
   
   
     7. The connector housing according to  claim 6 , wherein the crossbar fills in the final position of the front holder a gap between a wall of the first housing portion and of the outer face of the locking arms facing away from the accommodation chambers in a direction transversally to the longitudinal axis.
